Niger, abdomine fasciis duabus albidis, secunda latiore. Mesonotum fortiter punc- 

 tatum, interstitiis nitidis, distincte punctulatis. Propodeum opacum subobsolete punctatum, 

 concavitate rugulosa, baud evidenter punctata. Segmentum secundum abdominis fere ad 

 medium subfortiter elevatum, subtus depressione distincta. ^ ?. Long. 8|— 12-| mm. 



Black, with two pale bands on the abdomen. Thorax strongly punctured, meso-

Black, with two whitish abdominal bands. The (/ has also the clypeus and more or

 and the surface between the punctures is shining. The entire propodeum is rugose. 

 Abdomen with the basal segment closely punctured, more coarsely in the ^ than 

 the $ ; second raised from the base rather strongly in the c/ ; beneath, the costae 

 are strong and very long and there is no depression beyond their apices. 



Hab. Kauai, in the mountains. Not rare.
